dtSearch Desktop with Spider,
dtSearch Network with Spider

dtSearch Desktop with Spider and dtSearch Network with
Spider instantly search popular file types on a PC or a
network.

Both products index and search (with highlighted hits) a
wide variety of local and network content, including PDF,
HTML and XML files; word processor, database, spreadsheet,
presentation and similar "Office" files; ZIP files; and
email messages (Outlook Express, Outlook, Exchange, Eudora,
.MSG and other email formats) along with the full-text of
attachments. Through the dtSearch Spider, both applications
also support adding Web-based content to a local or
networked search.

dtSearch Publish

dtSearch Publish offers easy publishing of an instantly
searchable document collection to CD, DVD or other portable
media. The product can also mirror an existing Web site on
CD/DVD. The resulting CD/DVD application runs with "zero
footprint" on the end-user’s computer.

dtSearch Web with Spider

dtSearch Web with Spider quickly publishes a large volume
of instantly searchable data to an Internet or Intranet
site. Visitors accessing the site can instantly search with
hithighlighted display of Webready content (HTML, PDF, XML),
including WYSIWYG display of all images, formatting and
links. dtSearch Web automatically converts other file types
("Office", Unicode, ZIP, etc.) to HTML for browser display
with highlighted hits, making non- Web-based files
"Web-ready".

dtSearch Web installs through an easy wizard-based setup.
The application offers numerous customisation options, so
all aspects of the dtSearch Web display can match the style
of the rest of the site.

Operating through dtSearch Web, the Spider can expand the
scope of the searchable database beyond a site’s own data to
static and dynamic content on third-party sites.

The dtSearch Engine lets developers add dtSearch’s
builtin file format support and searching to Web-based and
other applications. The dtSearch Engine for Linux offers
APIs in C++ and Java. The dtSearch Engine for Win & .NET
includes sample code and API support for C++, Delphi, Java,
and .NET—including C#, VB.NET, ASP.NET and ADO.NET. (See
over for special database options for SQL and XML, and other
fielded data information.) The dtSearch Engine also includes
a .NET Spider API.

dtSearch Spider

The dtSearch Spider embedded in multiple dtSearch
products provides integrated searching of remote Web site
content, along with local data. In addition to support for
the file formats above, the dtSearch Spider can also index
and search dynamically generated content, such as
ASP/ASP.NET, MS CMS, SharePoint, etc.

dtSearch Features

Over two dozen search options

The dtSearch product line generally offers over two dozen
indexed, unindexed, fielded and full-text search options.

dtSearch also offers Unicode support for hundreds of
international languages, special forensics options, and
advanced database search options.

How dtSearch Works

dtSearch can instantly search terabytes of text
because it builds a search index that stores the
location of words in documents.

Indexing is easy—simply select folders or entire
drives to index and dtSearch does the rest.

dtSearch automatically recognises and supports all
popular file formats, and never alters original files.

A single index can hold over a terabyte of text (up
to billions of documents).

dtSearch can also create—and search with a single
search request—an unlimited number of indexes.

Since you may sometimes want to search files that
dtSearch has not indexed, dtSearch also does unindexed
as well as "combination" searching.

See more details below on file format support and
hit-highlighted display.

Basic Search Types

Phrase searching finds phrases
like:
due process of law.

Boolean operators like and/or/not
can join words and phrases: due process of law and
not (equal protection or civil rights).

Proximity searching finds a word or
phrase within "n" words of another word or phrase:
apple pie w/38 peach cobbler.

Relevancy ranking in a natural
language search is based on the frequency and density of
hits in your files.

For example, in the search request get me Sam's
memo on the 1999 CorpX takeover, if 1999
appeared in 3,000 files, and Sam appeared in
only two files, then Sam would get a much
higher relevancy rating, taking you straight to the most
relevant files.

A positional scoring option ranks
documents more highly when hits are near the top of a
file, or otherwise clustered in a file.

Variable term weighting works with
both natural language searching and structured search
requests to provide additional positive or negative
weighting to user-specified terms.

Variable term weighting can also apply to document
fields.

OCR and Imaging

dtSearch supports the PDF "image with hidden text"
format, and highlights hits
right on the scanned image in this format.

dtSearch also supports combined text and image
display in HTML and other Web-based formats.

FindPlus Distributed Searching

Through FindPlus, a single search request can span
multiple local and remote locations.

For example, a single search request can span
multiple indexes residing on a hard drive, a local area
network, an Intranet server, and even a
publicly-available Web server.

The same search request can then return
comprehensive search results from all locations, ranking
all retrieved files by relevance, and instantly
re-sorting, for example, by file date.

FindPlus will display all retrieved files with
highlighted hits (as well as HTML, XML and PDF links,
images and formatting), even if the files reside on
remote servers.

FindPlus distributed searching uses an XML-based
protocol for streaming search results, making it easy
for developers to integrate this feature into
applications.

Using related technology, the dtSearch Spider embedded in
multiple dtSearch products supports indexing with instant
searching of combined remote Web site and locally available
data.

In addition to PDF, HTML, XML, "Office" documents,
ZIP repositories, and the like, the dtSearch Spider can
also index and search dynamicallygenerated content, such
as ASP/ASP.NET, MS CMS and SharePoint.

The Spider can follow links vertically within a URL,
or horizontally across URLs, to any specified level of
depth.

Search filter objects allow multiple users with
different security classifications to search the same
document collection, without having to maintain separate
indexes corresponding to each classification level.

A single query can include an "exact phrase"
full-text end-user search request; second-level Boolean
search expressions (such as one or more field or
metadata search criteria); and developer-added filtering
expressions (such as a filtering expression to filter
out documents that do not match a user’s security
classification).
